No one has ever borrowed either of my machines. I might let someone sew on my older Viking 500 (in my home under my supervision) but it was my first "expensive" machine and I'm pretty attached to it, so maybe not. As for my other machine, no one touches my Bernina 730E but me! I always think of my dear neighbor, who back in the day bought a new Janome Memory Craft 8000 that her daughter begged and pleaded to borrow...then she took it home and dropped it down a flight of stairs!
